Loading Monterey has done something that prevents time machine from accessing my BU HD. The drive was checked using Disk Utility, it is fine. What did Monterey do automatic Time Machine BUs?
iMac 27″, macOS 10.15
Hello Stormy LC.
Thank you for using Apple Support Communities. From what we gathered, it sounds like you're experience issues with not being able to create Time Machine backups using your external hard drive. Specifically, this issue started to occur as soon as you updated your macOS version to Monterey. If this is the case, we'd like to share a helpful resource with you.
If you're unable to back up using Time Machine, the resource below might be able to help you:

We hope this information is useful. Cheers.
same for me here, after upgrading to Monterey the backup cannot complete at all. The setup did not change since Big Sur, same network drive on Synology NAS. On Big Sur it all worked just fine. I even tried removing existing backup but no avail, this is definitely the problem with Monterey
I ran disk utility, and it finished with no errors. I did a cold boot, and voila -- time machine working fine on my iMac 27" 5K 2019 computer. I then loaded Monterey on my MacBook Air 2021 with M1 CPU, same problem ( could not BU to the external drive that had been working flawlessly). I ran disk utility, did a cold boot, and all now working perfectly.
Based on your question marks, I will elaborate. On my 27" iMac 5K Retina 2019 3.7GHZ i5 CPU computer running Monterey, I opened FINDER, selected APPLICATIONS, scrolled down to UTILITIES, and selected DISK UTILITY. When it opened, I selected FIRST AID, it brought up my Hard Drive name, I selected it and after 10 minutes the report came back indications everything was fine, no issues. I then POWERED DOWN my computer, waited 30 seconds, and POWERED UP my computer. I initiated a Time Machine backup and all went smoothly. Problem solved. I had the same problem on my 2021 MacBook Air with the new M1 CPU, after I installed Monterey. I repeated the above process and voila -- time machine worked perfectly.
Thanks. I assumed that and did exactly that - but to no avail. Timemachine is still stuck at "waiting to complete the first backup".
I am really disappointed - none of the recent Mac OS releases worked from the start. All had surprisingly severe bugs.
nothing worked for me, something is really broken with time machine on Monterey, I even tried 12.1 beta. I also tried first aid on all drives, booting in safe mode, deleting timemachine sparsebundle from network drive and backing up from scratch. Now I am trying to decrypt the drives and see if it helps

Depending on how much data you have on the drive and the type of drive, it could take some time before completing the first backup, especially a a system upgrade.
"Run disk utility" = first aid, or what?
"Cold boot" = what?
Time Machine , immediately following update to Monterey unable to write to my Time Machine ext HD
